SPECIFICATION forming part of Letters-Patent No. 776,831, dated December 6, 1904.

Application filed November 16, 1903. Serial No. 181,375. (No model.)

T0 all whom, t may concern:

Be it known that l, SIMPSON L. Gnnnns, a citizen of ,the United States, residing at Vellington, in the county of Sumner and State of Kansas, have invented a new and useful Device for Holding Tires for Heating, of which the following is a specification.

This invention relates to devices 'for holding tires for heating, and has for its object to provide a device of the character described by means of which one or more tires may be easily and quickly secured and held above a forge or in front of the flame of an oil-burner or blast-lamp.

Afm-ther object of the invention is to provide in a device ot' the character specified improved operating devices by means or' which the tire-engaging arms may be simultaneously brought into engagement with the tire at a plurality oi' different points and the tire held with its center coincident with the center of the supporting device.

A 'further object of the invention is to provide an improved form of tire-engaging arm by means oil which the device is adapted to engage tires which have been distorted from true circular form.

A further object oi the invention is to provide an improved attachment Jfor each supporting-arm to adapt the device for simultaneously presenting a plurality of tires to the source of heat.

In the attainment oit' the objects above mentioned and others which will appear as the invention is tully disclosed I make use ot' the construction and combination of parts oi" a device for holding tires for heating shown in preferred form in the accompanying drawings, described in the following speciiication, and having the novel features thereof specifically pointed out in the appended claims.

In the drawings, Figure l is a view, partly in side elevation and partly in section, of the preferred form of the invention in operative position. Fig. 2 is a view, partly in side elevation and partly in section, showing a modilied form of the invention designed 'for use with a blast-lamp as the source of heat, the tire-engaging bars being provided with attachments for holdingI two or more tires. Fig.

is a front view of the spider and tire-engaging bars with the cam-plate removed. Fig. t is a view in perspective of the cani-plate from the rear. MFig. 5 is a view of the parts ot' one of the tire-engaging bars unassembled.

Referring to the drawings, in which corresponding' parts are designated by similar characters of reference throughout, l designates a base-plate, preferably square in outline, on which are secured by small bolts 2 or otherwise a plurality oi' radially-arranged supporting-arms 3, in this instance four in number, which lorm, together with the base, a spider upon which the tire-engaging bars are slidably supported. Each oit' the arms 3 is provided near its inner end with a bracket 4, consisting' of a base portion 5, which is secured upon the arm by means of the bolts 2 and the upturned slotted portion 6, which serves as a guide for the liattened inner end of one of the tire-engaging bars. Each oit' the arms 3 is provided at its outer end with a somewhat smaller bracket 8, which consists of a base portion 9, secured upon the bar, and an upturned end portion l0, having a round opening therein `for the passage ot' one of the tireengaging bars.

Each oiE the tire-engagingbars is preferably formed oi two sections, an inner section l2 and an outer section 13, the two sections being lapped, as shown, and connected by a pin 14: on the inner section, which engages aslot 15, formed in the outer section. The sections 12 and 'i3 oil each of the tire-engaging bars are prevented from separation by relative lateral movement by means of a coiled spring 16, wound around the overlappingportions oi" the two sections and secured between pins 17', extending through the two sections at suitable points. The inner end oi inner section l2 is flattened, as shown at 1S, and is provided with two or more kei-fs 19 for engagement with a cam-rib 2O on the inner surface ol" a circular plate 2i, which is rotatably mounted upon a pivot-pin 9.2 at the center of the apparatus. rlhe outer section 13 of each of the tire-engaging bars has a pointed outer end, as shown, which is adapted for engagement with the interior surface of an ordinary metal tire and is also provided with a transverse opening 23, whose utility will be hereinafter explained.

The plate 2l, with the cam-rib 2O on the inner surface thereof, which engages the kerfs 19 in the inner ends of the tire-engaging bars. forms the means for simultaneously projecting the several tire-engaging bars through the brackets provided on the supporting-arms of the spider. To facilitate the turning of the plate 2l, a pair of pins or handles 24 are provided on the outer surface of the plate at points near the periphery thereof, and in order to limit the outward movement of the tireengaging bars under the iniiuence of the camplate one of the bars is provided with a plurality of openings 25 in the flattened end 13, and a pin 26 is fixed in one of said openings to limit the outward movement of the bar by contact with the upturned end 6 of one of the brackets 4. As the outward movement of all of the tire-engaging bars is brought about by means of the cam-rib 20, the movement of all the bars outward will be checked whenever the movement of one is checked, and consequently the pin 26 serves to limit the outward movement of the entire set of tire-engaging bars.

In order to support the spider, with the mem.- bers carried thereby, above the fire of an ordinary forge, I provide an extensible bracket 30, comprising an arm 3l, with a slotted base 32, by means of which the position of the bracket may be adjusted, and a slotted extension 33, which is secured in adjusted position on the arm 3l by means of a thumb-screw 34, passing through a hole in the arm 3l and the slot in extension 33. The spider, with the brackets carried thereby,is rotatably supported on the bracket 30 bypassing the end of the pivot-pin 22 through the opening provided therefor in the upper end of the extension 33, and when the spider is so supported a tire held by the tire-engaging bars can be carried through the forge-lire and all portions thereof successively heated.

I/Vhen it is desired to support two tires for simultaneous heating, a member 36, having' a socket 37 of suitable size to receive the end of one of the tire-engaging bars, is iitted over the end of each bar and secured in position thereon by means of a pin 3S passing' through openings 39 in the socket 37 and through the opening 23 in each tire-engaging bar adjacent tothe outer end. Each member 3G has a face 40, which is perpendicular to the plane in which the tire-engaging bar is moved, and at one end of each member' 3G there is formed an outwardly-projecting lug 4l, which forms a shoulder against which a tire may be pressed to hold it in proper position while another tire is being' placed upon the members 36.

In order to secure a single tire only upon the device, the tire-engaging bars will be protire-engaging bars in the position shown in Fig. 3 and will be secured in that position by turning the plate Q1 in the direction indicated bythe arrow Xuntil further movement of the tire-engaging bars is stopped. After a tire has been sulliciently heated the tire-engaging bars will be retracted by turning the plate in the direction opposite to that indicated by the arrow X and the tire removed from a holder and applied to the wheel in the usual manner. `When itis desired to heat a tire by means of a blast-lamp, the spider, with the structures nounted thereon, will be supported upon an attachment 45, comprising a member 46, in one end of which the pivot-pin 22 of the spider is secured, and a member 47, having a slot 48 to receive a bolt 49, by which the members 46 and 47 are connected. The member 47 affords support for the blast-lamp, (not shown,) which is seated upon a plate at the outer end of the member 47. supported upon the attachment 45, the arms are disposed in a horizontal instead of a vertical plane and the Haine of the lamp is projected horizontally in the usual manner.

As the lamp by means of which heat is applied to the tire may be of any preferred construction and forms no part of the present invention, any description or illustration of the lamp for the purpose is regarded as superfluous.

Having thus described the nature and use of my invention, what I claim as new, and desire to secure by Letters Patent, is-
